\section{What else ...}
This application is an academic project for educational purposes. For this reason this project is not totally finished, but at 
least what we have already done can be the seed that results in a large application with many uses. 

We suggest that the priority improvements has to be related with security, for example using SSL to communicate with the server 
or being careful with some attacks like SQL injection, sniffing, DoS, etc. Furthermore it is highly recommended to distribute 
the web services host, as well as the database, in order to avoid the system's overload.

It is also important to upgrade the application with some privacy concerns, like offer the opportunity to the user to hide 
his current location or it can be limited to identifying the city only. It would also be important to expand the number of 
users who can enjoy the application, because currently is compatible with phones that have GPS and Android. Moreover, it would be 
interesting to have a multi-platform application that allows users to enter their different locations manually without relying 
on GPS or operating system. Other more complex upgrades could be make free calls by Internet, video calls, and a chat. Also it 
could be attractive to share user's information with some social networks like Twitter or Facebook.

The Web site could also be improved by adding interaction to the map, such as displaying notes or photos. In addition, actions 
like searching for friends and making friend requests can be developed in the Web site application.

As was mentioned before, this project can evolve in different ways, like being used by companies who want to know in real time 
where their employees are, or used as a kind of social network.
